AstGen: improved logic for nodeMayNeedMemoryLocation
* `@as` and `@bitCast` no longer unconditionally return `true` from
this function; they forward the question to their sub-expression.
* fix `@splat` incorrectly being marked as needing a memory location
(this function returns a SIMD vector; it definitely does not want a
memory location).
Makes AstGen generate slightly nicer ZIR, which in turn generates
slightly nicer AIR, generating slightly nicer machine code in debug
builds.
It also means I can procrastinate implementing the bitcast_result_ptr
ZIR instruction semantic analysis :^)
